Special Install/Upgrade Instructions for Existing OLI users for Unisim Design
Contents
Why the special Instructions?
History
In approximately 2005 Honeywell purchased the 'Hysys' code from Aspen Technologies and created Unisim Design. Hysys, at the time, supported the OLI Engine. The OLI Engine was a separate install for Hysys. Unisim Design R350 was the first version of Unisim Design and used the OLI installation package "As is."
With Unisim Design R360 Honeywell requested the the OLI Engine installation be bundled as part of the overall installation package for Unisim Design. OLI complied and provided the files necessary to complete this work. The advantage is that the user did not have to be bothered with two installation packages. The OLI engine installation appeared to be a silent install.
A reoccurring problem began to appear with this arrangement. The Unisim Design program was only being released approximately every 12 months. The OLI Engine program was being released approximately every quarter. This meant that after only a short time, the two programs would not be in sync. Users complained that answers in the OLI stand-alone code (such as the OLI Studio program) did not agree with the current version of the OLI engine in Unisim Design. Because of the single installation package, it was not possible to update the OLI Engine for Unisim Design.
Another problem that occurred is that OLI's customers would contract for new data to be added to the databases. OLI would then complete the addition and then not be able to update the OLI Engine for Unisim Design until the next release of Unisim Design. This was proving to be extremely inconvenient for several of OLI's largest customers.
With the release of UniSim Design R430 the situation has changed. The OLI Engine for Unisim Design is once again a separate installation package controlled by OLI Systems. Although it is still a silent installation a customer purchases UniSim Design from Honeywell with the OLI Engine, OLI can now update the engine when new data is released. If a new database is created then an end user can download the OLI Engine for UniSim Design from the OLI Downloads Website
Security Model Update
Since OLI Systems now controls the updates of the OLI Engine for UniSim Design we needed to update the security model. When you install the OLI Engine for Unisim Design you will also need a serial number obtained from OLI Systems. Depending on your licensing options you may also need a physical hardware device known as a dongle
or a softkey. You may also need to download and install the OLI Network License manager (which requires either a dongle or a softkey).
